Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for binding assay substrata fail to provide a stable and protective environment for biomolecules, leading to degradation and inaccurate measurements in biochemical assays, particularly in mass spectrometry techniques like MALDI and SELDI, due to denaturation of sensitive proteins and poor substrate binding.
Innovation Solution
The use of lyotropic liquid and liquid crystalline materials that stably bind to assay substrata, encapsulating biomolecules and protecting them from degradative enzymes and denaturing effects, while promoting robust substrate binding and reducing run-to-run variability and increasing signal-to-noise ratios.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional binding methods are used for assay substrata, then the assay can be performed, but the biomolecules are exposed to degradative enzymes and denaturing effects, leading to degradation and inaccurate measurements
Solution Approach 1:
The patent employs lyotropic liquid crystalline materials as intermediary substances that form a protective barrier between the biomolecules and the harmful assay environment. These materials bind to the substrata and create a stable, protective microenvironment that shields sensitive proteins and standards from degradative enzymes and denaturing effects, thereby maintaining biomolecule integrity during the assay process
Solution Approach 2:
The lyotropic liquid crystalline materials create an inert, protective environment around the biomolecules on the substrata. This environment is chemically stable and resistant to degradation, effectively isolating the biomolecules from harmful external factors such as proteases, nucleases, and other denaturing conditions present in the assay system
2Measurement precision
If standards are added to biological fluids for calibration, then charge/mass ratio and intensity can be calibrated, but the standards are degraded by proteases, lysozyme, trypsin, nucleases and other compounds in the biological fluids
Solution Approach 1:
The lyotropic liquid crystalline materials serve as protective intermediaries that bind the calibration standards to the substrata in a stable configuration. This protective binding prevents proteases, lysozyme, trypsin, nucleases and other degradative compounds in the biological fluids from accessing and degrading the standards, thereby preserving their integrity for accurate calibration measurements
Solution Approach 2:
The patent applies the protective lyotropic liquid crystalline coating to the substrata beforehand, before adding the standards to biological fluids. This pre-established protective barrier cushions the standards against upcoming exposure to degradative enzymes, ensuring their survival and maintaining calibration accuracy throughout the assay process
3Measurement precision
If multiple standard molecules are used for better calibration, then calibration coverage is improved, but run-to-run variability of peak positions and intensities confounds the calibration
Solution Approach 1:
The patent applies lyotropic liquid crystalline materials with specific local properties optimized for binding and stabilizing multiple different standard molecules. Each standard molecule benefits from the localized protective environment created by the liquid crystalline coating, ensuring consistent binding and stable peak positions and intensities across multiple standards and runs
Solution Approach 2:
The lyotropic liquid crystalline materials modify the physical and chemical parameters of the substrata surface, creating a uniform and stable binding environment. This parameter modification reduces variability in peak positions and intensities by ensuring consistent interaction conditions for all standard molecules across different runs
4Quantity of substance
If solid surfaces are used to concentrate dilute species, then quantification is improved, but delicate proteins such as receptors denature or flocculate
Solution Approach 1:
The lyotropic liquid crystalline materials act as intermediary substances that mediate between the solid substrata and delicate membrane proteins. These materials bind to the substrata and provide a protective, biomimetic environment that maintains the natural conformation and functionality of membrane-associated proteins while still enabling effective concentration and detection of dilute analytes
